CLOSURE FOR ICE BAGS.

Application filed November 10, 1921, Serial No. 514,253. Renewed April 30. 1926.

This invention relates to closures for ice bags, and aims to provide certain improvements therein. The invention is particularly directed to an improvement in a device of the class described, wherein the closure iS formed with a nipple or socket member,

which is connected with the bag and a cap tomprislng a metal structure having in the preferred form a central aperture at its top with apackinggasket .on the under side of theflange formed. bythe aperture, and a covering forming preferably an integral structure with the packing gasket.

The present invention is an improvement.

uponthis general construction, by means of which the fastening of the closure to the ice bag is simplified and the entire structure cheapened.

According to the present invention the socket member and cap are formed of sheet metal, and the socket member is connected to the bag by a threaded sleeve, thus avoidthe necessity of vulcanizing the socket member to the ice bag. The invention also includes certain other features of improvement which will be hereinafter more fully pointed out.

Referring to the drawings, which illustrate several forms of the invention,

Figure l is an elevation of the socket member and sleeve, the cap being partly shown with the covering in section.

Fig. 2 is a diametrical section.

3 is a view, showing various sections on the lines 3-3 in Fig. 2.

F t shows another form of the invention in diametrical section.

Fig. 5 is an elevation of her of Fig. 4.

Fig. 6 is a diametrical section of another form of the invention.

Fig. 7 is an elevation of the metallic cap, socket member, and sleeve of Fig. 6.

Fig. 8 shows sections taken on the lines S-8 in Fig. 6. 1

Referring firstto Figs. 1 to 3 of the drawings, let A indicate a socket member, which is shown as formed of'sheet metal, having a thread B rolled thereon and having a bottom flange C. Preferably the bottom'flange has its edge turned over at D, so as to prevent cutting of the rubber. The socket memher is inserted within the neck of the rubber bag, the flange C lying beneath the wall of the latter, and preferably the wall being reinforced by a patch of fabric or rubber F.

the socket mem- Screwing on the exterior of the socket member is a clamping sleeve G, which is also preferably formed of sheet metal, and is provided with a flange H adapt-ed to engage the upper side of the body of the ice bag, where by when screwed home the bag is clamped between the flanges C and H and thus adequately held in place. In theconstruction shown the metallicca'p member J is formed also of sheet metal, and has a thread rolled in. it. to engage the thread 13 of the socket member. The sheet metal cap is perforated on its top, so as to leave a flange K, and the rubber cover L is moulded on the inside and outside ofthe flange, thus forming a pack,-'

ing which engages the seat M formed on the top or the socket member. Preferably the rubber covering is extended entirely over' the exterior of the cap.

The flange K is preferably corrugated as shown at N, so as to make a holding surface for the rubber. This produces a slight swell in the rubber around the interior of the cap where the packing'seats against the seat M, which is advantageous in that it provides a depressed ring around the packing which facilitates the forming of a tight joint with the seat, In order that the socket member may secure a better grip on the rubber of the bag, whereby to prevent loosening under torsional strainswhen the cap is being screwed and unscrewed, I provide projections 0 (see Fig. 3) which are stamped up from the flange C, and which enter the rubber when the clamping ring G r is screwed tight. Similar projections may be formed on the clamping ring, as shown for instance in Figs. 6 and 8. V

In Figs. 4: and 5 I have lllustratcd a mothfled form in which the socket member A is arranged on the outside of the bag, and the clamping sleeve G 18 arr nged on the inside. By this means the socket member 'may be very considerably shortened as com- I) of the socket member is made wider than e J of the interior clamping ring. the purpose of enabling the user ie flange D of the socket member e =:ap is being screwed on and unl. Under these conditions the screw and unscrewing ot the cap would have no tendency to loosen the clamping ring G While 1 have shown and described several the invention, it will be understood that i t wish to be limited thereto, as

A closure for ice bags or the like, comprising a socket member having a flange adapted to contact with the outer wall of a bag and an internal clamping ring having asimilar flange adapted to contact with the interio wall of the bag, said clamping ring screwing on the interior of the socket memher, and the clamping ring having a flange extending beyond the flange on the socket member.,

3. A closure for ice bags or the like, comprising a socket member having a flange adapted to contact with the outer wall of a bag and an internal clamping member having a similar flange adapted to contact with the interior wall of the bag, said clamping ring screwing on the interior of one of said members, and the socket member having a flange extending beyond the flange on the other member.

in witness whereof, Ihave hereunto signed my name.
